The horizontal spring is lying on a frictionless surface. One end of the spring is joined to a wall whereas the other end is joined to a movable object. The spring and object are compressed by 0.082 m, free from rest, and afterward oscillate back and forth with an angular frequency of 11.9 rad/s. Determine the speed of the object at the instant if the spring is stretched by 0.041 m relative to the unstrained length?
